Atlas V 70% 'Go' For Friday Launch



CAPE CANAVERAL, Florida -- The Atlas V launch of the Radiation Belt Storm Probes spacecraft has a 70% weather chance for launch at 4:07 a.m. EDT on Friday August 24, 2012 with a 20-minute launch window.


The USAF 45th Weather Squadron says that meteorological models are indicating less chance for cloud cover; therefore, the  probability of violating weather constraints decreased to 30%.
The primary concern for launch Friday morning is a thick cloud rule violation. Friday evening, easterly flow will set in as the front washes out and Tropical Storm Isaac moves into the Caribbean near Hispaniola, potentially as a category 1 hurricane. The primary concerns for a Saturday morning launch will be coastal showers causing a cumulus cloud violation.
